    Installation of borehole seismometers within the Alpine Fault Zone in the DFDP-1 boreholes to record Fault Zone Guided or Trapped Waves (FZGWs). These have been observed and can be used to establish fault zone connectivity and model the fault zone properties laterally and with depth. An explosive seismic survey has been carried out in 2012 at Gaunt Creek along a 2D profile through DFDP-1A across the fault with additional larger shots up to 10 km along the strike of the fault to induce FZGW.

    Core should comprise mylonite, cataclasite + principal slip surface. We will analyse mcro- and micro-fracture density and orientations, permeability structure, and make physical property measurements (p and s-wave velocities, frictional properties, permeability, paleopermeabilty, chemistry, magnetic susceptibility, etc...). CAT scans with a medical imaging system are planned.
